CNC Type B Hop-Up Chamber for M4 Series

The CNC Type B Hop-Up Chamber is a precision-engineered upgrade for your M4-series AEG gearbox, designed to deliver consistent backspin, improved accuracy, and enhanced range shot after shot. Machined from aerospace-grade 6061-T6 aluminum and hard-anodized in matte black, the Type B chamber features a tight, square-cut bore interface that perfectly houses standard M4 hop-up buckings. Its CNC-cut tolerances (±0.02 mm) ensure minimal air leakage and uniform BB compression against the bucking, producing a reliable and repeatable trajectory under all conditions.

Installation is straightforward: simply remove the stock chamber, install the Type B unit, and secure it with the original gearbox shell screws—no modification or shimming required. The chamber’s external profile matches your receiver’s internal contour, allowing unobstructed magazine insertion and slide movement. Internally, the precisely angled hop window aligns perfectly with the inner barrel, reducing hop-bucking wear and preventing flat-spotting on your BBs.

Ideal for competitive skirmishes, target practice, or precision field play, the CNC Type B Hop-Up Chamber enhances the performance of all 6 mm AEG BBs from .20 g to .36 g. Its durable anodized finish resists corrosion, abrasion, and heat from high-rate firing, while the lightweight design (approx. 25 g) adds negligible mass to your build. Upgrade to the Type B chamber for rock-solid FPS consistency, tighter groupings, and maximum effective range.
